Abstract: This invention concerns with a process and apparatus for fabricating microlenses on optical fibers. A pulsed laser beam and an end portion of a fiber are arranged relative each to another so that the laser beam is incident on the end portion of the fiber at an acute angle ϑ to the longitudinal axis of the fiber. The angle is selected to attain a desired curvature of a lens formed by ablation and heating of the end portion of the fiber by the laser beam. A movement of the fiber and the laser relative each to another results in progressive engagement of the end portion of the fiber with the laser for a preselected distance so as to produce a short taper with a lens at the end thereof. In the preferred embodiment, the fiber rotated about its axis within a passage of the holder which moves the end-portion of the fiber into and through the laser beam resulting in the said lens. The precise repeatability of the lens formation may be controlled by a computer.

Abstract: Un matériau élastique est utilisé comme couche de base de couches surjacentes d'une fibre optique enroulée sur une bobine. Dans une mode de réalisation, le critère de sélection de la couche de base est sa compatibilité avec un revêtement de la fibre optique. Dans un autre mode de réalisation, le matériau élastique (10) comprend un revêtement agencé sur la bobine. Dans un autre mode de réalisation, la couche de base comprend un matériau en silicium. L'utilisation d'un matériau élastique comme couche de base rend superflus la fabrication et le stockage d'un matériau coûteux pour cuches de base formé de fils métalliques. L'utilisation du matériau élastique doit également réduire les sollicitations de la première couche de fibre enroulée. En outre il est plus facile d'accorder les propriétés thermiques de la fibre optique avec les propriétés thermiques du matériau élastique (20) dans une large plage de températures que d'accorder les propriétés thermiques de la fibre optique avec le fil métallique qui forme la couche de base. Ainsi, on réduit la différence entre les caractéristiques de la dilatation thermique de la couche de base et de la fibre enroulée (25) dans une plage prévue de températures de fonctionnement, réduisant au maximum les risques de déroulement du paquet de fibres optiques sur la bobine pendant un stockage ou un dévidement prolongés.

Title: Interlock circuit for preventing corruption of telephone line signals.
Inventor: BENJAMIN DEAN L
IPC: H04Q1/44
Filed: 1990-01-31
Abstract: Corruption of communication signals on a telephone line (32, 33) by the direct (low impedance) interfacing of test equipment (20) to the line is precluded by a protective interlock circuit, which prevents the test set from seizing the line if data traffic is present. The interlock circuit is coupled between the line circuit to be accessed and the test equipment, and includes a multiple band frequency detector (31), which monitors the line for signals lying within (in and out-of-audio) frequency bands. Should the detector identify any traffic within its sensitivity range (out of the audio band) during the interval of a timing pulse produced by the closure of a switch (51), the logic level applied to combinational logic will change state and prevent the generation of a test set enabling signal.

The laminated material is suitable in particular for use as a drainage sheet or membrane. To produce the membrane, the thermoplastic foam in the form of strips, lengths, shreds or the like is piled up to form a layer of uniform height and compressed and compacted at a temperature below the softening temperature of the foam. Subsequently, the compressed and compacted layer of thermoplastic foam is perforated and fused with the aid of pins which are heated to a temperature of 400 DEG  to 800 DEG  C., whereupon the perforated and fused layer is cooled while maintaining the compression.

Abstract: In a method and apparatus (10) for cutting sheet material (22) wherein the material is cut in bites or segments (58) by bringing in stepwise fashion successive lengthwise segments (72, 74, 76) to a cutting station (26) incomplete cutting of a line (62) or pattern piece (58) when the line (62) or pattern piece (58) is continued from one segment (72, 74, 76) to another is avoided by a retracing of the line (62) of cut in the vicinity of the line's or pattern piece's transition from one segment to another. Therefore, when the cutting tool (32), following the advancement of the material (22) to bring a fresh segment to the cutting station (26), is returned to the vicinity of a previously cut point it retraces a portion of the previously cut line (62) to promote complete separation of the desired material from the waste material (60) despite possible relaxation or other shifting or mispositioning of the material (22) between the times of the cutting tool's first and second arrivals at the transition point.

Abstract: A method is described of determining a Doppler signal in a laser-Doppler anemometer, as is a carrier frequency laser-Doppler anemometer for carrying out this method. According to the invention, the measuring laser light is modulated with the aid of a high-frequency carrier frequency which is substantially higher than the Doppler frequency, and the laser light thus modulated by carrier frequency is then introduced into a laser-Doppler anemometer measuring volume. It is amplitude-modulated in this measuring volume with the aid of a Doppler frequency, thus resulting in a signal spectrum having a plurality of side bands. The side band that is positive and/or negative with respect to the carrier frequency is amplified in a resonance amplifier accommodating these side bands, and the positive and/or negative side band is then further processed in an evaluation circuit in order to obtain the Doppler information. This method enables the use of photodiodes that are easy to operate, and also the use of low-noise amplifiers of comparatively simple construction. <IMAGE>
